Key, I finally got my hands on a write protectable pendrive. It is a Kingston drive, with a write protect switch on the side. Installed DSL frugal_hdd to the pendrive, write enabled, of course! Then shutdown system. Placed the write protected standard boot floppy in foppy drive, and moved the switch on the pendrive to write protect. Plugged in the write protected pendrive and booted DSL. No problems.

The only way I can cause an error code to display, is when I add the boot option frugal. But of course, that would! Boot code frugal is not appropriate on a read only device.

I too am still testing this RC. Found more unconverted lines in icontool.lua, around 196 and again around 205. Easy to fix. But still the conversion of 50+ programs has been an arduous undertaking. It was worth doing. Still hoping to get everything fully tested and working before a final release. Appreciate those who have the patience to help me in testing everything.
